US3827556A Purification of kaolin clay by froth

A method for removing finely divided particles of a colored titaniferous impurity from a dispersed alkaline pulp of kaolin clay by froth flotation. The collector for the impurities is a very low rosin acid tall oil which also provides controlled frothing without the addition of hydrocarbon oils to prevent overfrothing.

Research on mineralogy and flotation for coal series kaolin

Research on mineralogy and flotation for coal series kaolin

The iron mineral was separated by froth flotation for the coal series kaolin. The mineralogy of the coal series kaolin was studied by several methods such as X ray diffraction (XRD), X ray fluorescence (XRF), particle size distribution and SEM/EDS analyses.

Dec 01, 2002Abstract. Kaolin is valued as a white pigment and therefore the goal in kaolin flotation circuits is to remove the colored impurities to result in an acceptable brightness product. Kaolin flotation originated with a novel carrier flotation process and later on carrierless flotation

Froth flotation

Froth flotation

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

PURIFICATION OF KAOLIN CLAY BY FROTH FLOTATION

PURIFICATION OF KAOLIN CLAY BY FROTH FLOTATION

Aug 06, 1974In a method for removing discrete colored titaniferous impurities from a fine size fraction of degritted kaolin clay wherein a dispersed alkaline pulp of the impure clay is subjected to froth flotation in the presence of an anionic collector for the titaniferous impurities and means is provided for imparting controlled frothing characteristics to the pulp, the improvement which consists of using as

Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.

US4629556A Purification of kaolin clay by froth

An improved flotation process for removal of colored titaniferous impurities from kaolin clay uses as collector a hydroxamate compound, or a mixture of compounds, having the formula ##STR1## in which R is an alkyl, aryl, or alkylaryl group having 4 28, and preferably 6 24 carbon atoms, and M represents an alkali metal, an alkaline earth metal or hydrogen.

However, the beneficiation of kaolin, a naturally occurringfine ore, via flotation has been practiced over the last 40years. Kaolin is valued as a white pigment, and therefore, the goal in kaolinflotation circuits is to remove the colored impurities to result in an acceptable brightness product.
